摘　　要：在分析了IPVPN(基于网际协议的虚拟专用网)业务多链路、多QoS(服务质量)等级的特点后,提出了IPVPN业务在业务提供、业务保证和QoS综合评价方面的特殊管理需求.针对这些特殊需求,研究了包含服务、技术和商务内容的IPVPN业务管理SLA(服务等级协定)模板,以及基于eTOM(增强的电信运营图)框架和管理流程原理的IPVPN业务保证方法.After analyzing the multi-links and multi-QoS (quality of service) classes characteristics of IP VPN (IP based virtual private network), the special requirements of IP VPN management in service fulfillment, service assurance and integrated evaluation of QoS are proposed. Based on these requirements, an SLA (service level agreement) template comprising items of service, technology and business for IP VPN service management is proposed, and the method of IP VPN service assurance which is based on eTOM (enhanced telecom operations map) framework and management process theories is studied.
